Press Association Sport understands the two clubs have reached an agreement over the £4.7million-rated 24-year-old, who could head for Tyneside within the next 24 hours to clinch a move.

Riviere would become Pardew's fifth summer signing, with Holland defender Daryl Janmaat yet to formally complete his switch to Tyneside from Feyenoord.

Newcastle's striking department was decimated at the end of last season by the departures of loan signings Loic Remy and Luuk de Jong and the out-of-contract Shola Ameobi, while Papiss Cisse is currently recovering from a knee injury.

Summer signing Siem de Jong played in an advanced role last night as Pardew has suggested he could do on a regular basis if required, although he is regarded more as a midfielder.

Riviere's capture would begin to address that particular issue, although it would be unlikely to end the Magpies' search for reinforcements with Lyon's Alexandre Lacazette among a series of other potential targets.

The latest potential arrival made 30 appearances for Monaco last season and scored 10 goals.

Meanwhile, Newcastle's proposed unveiling of Janmaat, which was initially expected on Tuesday afternoon, is now unlikely to take place on Wednesday either, although the delay is purely administrative.

Janmaat has been signed to replace France international Mathieu Debuchy, whose proposed move to Arsenal has been on hold while the Magpies have tied up the Dutchman.

The Gunners are confident they have a deal in place, although Paris St Germain, who took Debuchy's close friend Yohan Cabaye from St James' Park in January, have a long-standing interest in him.
